Sometimes the most impactful renovations are those that you can't even really see. That is the case with this amazing Park Slope, Brooklyn, townhouse that our very own Stylelist fashion editor, Christina Anderson, and her husband, Simon, recently renovated for their young family. This intensive makeover included converting what was once a two-family building into a four-floor home and several much-needed updates to make the space both safe and efficient for the couple and their two children. And it doesn't look too shabby, either, as you'll see in our house tour.
